  1. Question 1

    Q1. A transformer is used to step-up the voltage in a power distribution system. What is the effect on current?

    • A) Increased
    • B) Decreased
    • C) No change
    • D) Depends on resistance

    Answer: Decreased

    Explanation: When voltage is increased in a transformer, the current decreases according to the inverse relationship between voltage and current. The other options do not describe the effect correctly.
